Funk-Electronic Piciorgros GmbH1TETRA System Structure for Data ApplicationsData applications for utilities, water/ wastewater, gas and oil and similar applicationscan be operated in different ways. Polling protocols, polling protocols (also) usingunsolicited messaging, protocols based on serial communication and protocols based onIP communication.The TETRA infrastructure can also be used in different ways to communicate the datamessages from one or more SCADA server(s) to the data outstations: SDScommunication, Packet Switched Data and Multi Slot Packet Data.1.1Serial Protocols on TETRASerial protocols can be sent as SDS or with PD.When sending as SDS messages care should be taken, as the lengths of SDS messagesdiffer from infrastructure to infrastructure, so it may take more time to transmit withSDS when the SDS length is not using the full TETRA specification of 254 bytes perSDS message.When sending data messages with PD (that will be the user’s choice if the TETRAinfrastructure does not support SSCH and he wants to avoid too much SDS traffic onthe MCCH), the serial data will be framed into an UDP/IP data frame and sent on trafficchannels.1.2IP protocols on TETRA1.2.1TETRA Packet Data FeatureWhen using IP communication over the TETRA network from end to end (SCADAserver to data outstation), the TETRA PD feature is the best choice. In this case one ormore TETRA time slots can be used simultaneously for the data transport (three timeslots on the first carrier, four on each of the additional RF carriers on the same BS).It is important to know that on each PD traffic channel more than one MS (outstation)can operate in “semi” parallel when Packet Data Channel Sharing is enabled on theinfrastructure. Even if simultaneous operation on a single time slot is not essentiallyneeded it is important to enable the packet data channel sharing, because once the datacommunication between the SCADA server and the outstation is completed, the MSwill stay on the PDCH until the Ready Timer (MS and Infra) has been elapsed – whichusually takes 3-5 seconds. And without packet data channel sharing this timeslot will beblocked and the SwMi will report on a new data transmission request from the SCADAServer with “No Resources”.End-to-End IP communication is easy to install on TETRA infrastructures, because nospecial data gateway needs to be installed on the SCADA server side and a simple IPconnection from SCADA Server to the SwMi (please contact your Infrastructuremanufacturer for more details) without any special API can be used.1.2.2TCP and UDP ProtocolsWith Packet Switched Data or Multi Slot Packet Data, IP communication can be usedon TETRA infrastructures. But when using standard PC applications like SCADAservers and TCP/IP (Protocols like: DNP3/IP, Modbus/IP, IEC60870-5-104), thetimeouts of the TCP/IP link are often too short to guarantee a smooth and effective dataTETRA Data Modem and TETRA Test Set - Page 2 of 12

Funk-Electronic Piciorgros GmbHcommunication over the TETRA network. Therefore the TCP/IP timing has to beadjusted on the SCADA server (mostly changes in the Windows registry are needed) toensure a proper operation over TETRA.In comparison to the TCP-Protocols, UDP is more efficient for TETRA because it doesnot use any additional “logical handshaking” and it can be seen similar as serial dataprotocols, where the SCADA Server and its data timeouts control the communicationlink.1.3TETRA Data Gateway for Serial ProtocolsTo avoid a “data bottle neck” on the TETRA network air interface on the SCADAservers side (here all data to and from all outstations has to pass from the SCADAserver to the TETRA infrastructure) a TETRA Data Gateway should be used betweenSCADA server and TETRA SwMi.The TETRA Data Gateway will receive all serial data frames from the SCADA Serverand will send it using a special API (in TETRA this interface is not specified, so eachTETRA infrastructure manufacture will have its own interface) to the data outstations.1.3.1Gateway Routing TableSerial protocols will always contain (there may be some exceptions on proprietary userprotocols) a destination address. Care has to be taken to NOT USE TETRA groupcommunication but send the serial data to an individual ISSI for each single dataoutstation. Therefore the TETRA Data Server needs to convert the serial data protocolreceived from the SCADA server into a TETRA message to be sent to an individualMS.1.3.2Gateway Data CompressionIn many cases protocols for utilities, water, wastewater, gas and oil, (more) are not veryefficient and can contain a lot of “00” or “FF” or similar data. In this case datacompression is useful to minimize the load and to use the TETRA network in the mostefficient way.TETRA Data Modem and TETRA Test Set - Page 3 of 12

Funk-Electronic Piciorgros GmbH1.4Optimizing the Data Throughput on TETRA networks1.4.1Data Throughput with SDS CommunicationWhen polling data (requesting data from the outstation) - using e.g. the Modbus RTUprotocol with an SDS message of about 10-15 bytes for the poll request and 100 bytesof responding data - a complete polling cycle in a live network will need about 1,5seconds (not including the field device (PLC) latency!). During that time period theTETRA network (time slots) will not be used efficient and most of the time being inidle state not carrying any data.When splitting the SCADA Server into several polling nodes and pollingsimultaneously on the same timeslot(s) the data throughput can be increasedsubstantially. De facto up to four (depending on the infrastructure) polling nodes on asingle time slot will (also) increase the data throughput by four times. Care has to betaken in this scenario, because the single response time for a single polling request canbe increased, and a suggested value for the SCADA Server polling timeout is about 3seconds1.4.2Data Throughput with PD communicationAs already mentioned above, it is essential that on Packet Data communication, theTETRA channel sharing for all of the used packet data channels has to be enabled,otherwise each single data communication to a single outstation device will block theused timeslot (logic channel) for the pre-programmed SwMi and MS “Ready Timer”.And as the data packets can be in different sizes and the outstation can respond withdifferent latency, the Ready Timer should be chosen not too short (suggested: 5seconds).TETRA Data Modem and TETRA Test Set - Page 4 of 12
